Embodiment Construction
[0027] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0028] The specific embodiment of the electric switch provided by the present invention, as Figure 1 to Figure 8 As shown, the electrical switch in this embodiment is specifically a grounding switch, including a switch operation shaft as a power input part. The switch operation shaft includes a mounting shaft section 8, and 5 mounting shafts are mounted on the mounting shaft section 8 in a non-rotating manner. The shaft fittings arranged in sequence in the axial direction, the shaft fittings in this embodiment are all fan-shaped plate structures, corresponding to the first fan-shaped plate 9, the second fan-shaped plate 7, the third fan-shaped plate 5, the fourth fan-shaped plate 3 and the fifth Sector plate 2.
[0029] In this embodiment, the installation shaft section 8 is specifically a hexagonal prism structure, which has six outer contact planes d...

The invention relates to a switch operation shaft with a function of wrong-mounting prevention, shaft fittings and an electrical switch. The electrical switch comprises the switch operation shaft, the switch operation shaft comprises a mounting shaft section, the mounting shaft section is provided with at least two shaft fittings arranged in the axle direction of the mounting shaft in a turning-stopping mode, a turning-stopping hole is formed in each shaft fitting, the mounting shaft section is provided with a turning-stopping outer circumferential surface, the turning-stopping hole is provided with a turning-stopping inner circumferential surface which is matched with the turning-stopping outer circumferential surface in an inserted mode, the turning-stopping outer circumferential surface is provided with an outer wrong-mounting prevention face section which is arranged in the circumferential direction of the mounting shaft section, the turning-stopping inner circumferential surface is provided with an inner wrong-mounting prevention section which is arranged in the circumferential direction of the turning-stopping holes, and the inner and outer wrong-mounting prevention sections are matched correspondingly to the shaft fittings mounted on the mounting shaft section in a positioning mode in the circumferential direction of the mounting shaft section according to corresponding mounting angles. The inner and outer wrong-mounting prevention sections are utilized to ensure the correct mounting angles of each fan plate on the mounting shaft section, and therefore the reworking problem caused by wrong mounting does not occur, and the mounting efficiency can be effectively improved.
Description
technical field [0001] The invention relates to a switch operation shaft, a shaft fitting and an electric switch with the function of preventing wrong assembly. Background technique [0002] In electrical switching equipment, both the electric operating mechanism and the manual operating mechanism are equipped with a switch operation shaft as the power input part. The switch operation shaft realizes the control action of the corresponding electrical switch through the transmission mechanism, and then controls the corresponding circuit on and off. [0003] For example, the electric operating mechanism of the earthing switch disclosed in the Chinese utility model patent whose authorized announcement number is CN201478144U includes a base on which an operating shaft assembly is arranged. The operating shaft assembly includes a hexagonal operating shaft on which a The power output part realizes the opening and closing operation of the grounding switch by controlling the rotation...
